IntroductionWelcome to the "Mastering Apache Web Server and NGINX" course! This comprehensive course is designed to take you from a beginner to an advanced user in web server management. Throughout this course, you will gain hands-on experience with Apache Web Server and NGINX, two of the most popular and powerful web servers used in the industry today.The course is divided into four sections, each focusing on different aspects of web server management and application development. Starting with the basics of Apache Web Server, you will learn how to set up and configure your server, create dynamic web pages with PHP, and manage user directories and permissions. You will also dive into advanced topics such as virtual hosting, log management, and using .htaccess files for configuration.In the later sections, you will explore NGINX, learning how to manage this powerful web server and compare it with Apache. The course includes real-world projects that will help you apply your knowledge and develop practical skills. By the end of this course, you will be well-equipped to manage and configure web servers for professional web development tasks.Section 1: Learning Apache Web Server with a ProjectIn this section, students will embark on a hands-on project to learn the fundamentals of the Apache Web Server using the XAMPP server. Starting with an introduction to the project, students will set up and configure their environment. They will then dive into creating a structured website, learning how to build and customize various components, including headers, footers, and multiple pages such as the index, about, services, and contact pages. By the end of this section, students will have a fully functional website and a solid understanding of Apache Web Server basics.Section 2: Apache Web Server Management and NGINXThis section transitions from basic Apache Web Server usage to advanced management techniques and introduces NGI

Welcome to NestJS Unleashed! In this section, I will explain the problem this course aims to address, its purpose, and finally its structure.ProblemNode.js is a backend JavaScript runtime environment that gained high popularity in recent years, and one of the reasons for it is because it allows for using the same programming language (JavaScript) for both frontend and backend development, amongst others. Even then, if used by itself, it is a quite "crude" environment for development as you are responsible for:Libraries configurationCode architectureRoutingAmong other thingsTo develop robust systems, in a professional fashion, it may not be so interesting to write code in pure Node.js. Many times, you may find yourself "reinventing the wheel" when there are already established and refined solutions, and it may become increasingly harder to maintain the system over time. In summary, this is the problem that this course aims to solve.PurposeThe main intention of this course is to show how to harness most of the potential of the NestJS framework, which arose quickly in recent years. We'll do so while focusing on elegant architectural solutions, while learning everything in an intuitive and pleasing manner.Here, all the lessons will be taught using a completely practical approach, and we will study theory only when necessary to solve problems that arise during our journey. The course is also incremental, meaning that we will start developing our backend system from scratch and improve it with more functionalities and upgrades along the course.An important note, the approach to the architecture and code design used here is akin to a proposal. There is no completely perfect and flawless way of deve

This course is designed on the concept of SAP Fiori by SAP S/4 HANA system. SAP Fiori is evolving rapidly in the market and companies are using its applications for their business tasks. To comprehend the need of SAP Fiori, I want to create a course which will be based on SAP Fiori application. This course will benefit any person who wants to learn Material Management in SAP Fiori launchpad instead of SAP GUI. Besides this, it will also cover the customization, personalization, integration and formation of groups in tiles and links.If you want to become a SAP MM Consultant or an End User in SAP MM than this course will help you to work in any SAP based firm as it will cover all aspects of MM. By the end of this course, you will be confident enough to apply your knowledge in the real world.As this course is only based on SAP Fiori, so it will not cover SAP GUI. This will only teach you SAP MM transactions and how to work with Fiori apps particularly transactional apps. Moreover, it has a plus point as in near future, companies will start moving towards mobile computing and they will hire employees who have knowledge of using SAP Fiori apps for procurement process on their mobile devices instead of using company computers to post small business transactions.In SAP MM, I will teach you how to maintain business partner by creating vendor in the SAP Fiori, create material, purchase requisition, RFQs, different types of purchase orders, service master data, manage stock, create goods receipt, transfer posting, create supplier invoice, post outgoing payments and many other concepts. Throughout the whole course, my intention is to clear your concepts about each term and if I missed anything as MM is a vast field, you can highlight that, and I will try my best to update you with information.*Disclaimer*SAP is a registered trademark of SAP AG in Germany and many other countries.
